The first named storm of the 2008 North Indian Ocean cyclone season, Nargis developed on April 27 in the central Bay of Bengal. Initially it tracked slowly northwestward and, encountering favorable conditions, it quickly strengthened. Dry air weakened the cyclone on April 29, though after beginning a steady eastward motion Nargis rapidly intensified to attain peak winds of at least 165 km/h (105 mph) on May 2; the Joint Typhoon Warning Center assessed peak winds of 215 km/h (135 mph). The cyclone moved ashore in the Ayeyarwady Division of Burma near peak intensity and, after passing near the major city of Yangon (Rangoon), the storm gradually weakened until dissipating near the border of Burma and تايلند.

In the last week of April, an area of deep convection and concern persisted near a low-level circulation in the Bay of Bengal about 1150 km (715 mi) east-southeast of Chennai, الهند.[4] With good outflow and low wind shear, the system slowly organized as its circulation consolidated.[5] At 0300 UTC on April 27, the India Meteorological Department (IMD) classified the system as a depression,[6] and nine hours later the system intensified into a deep depression.[7] At the same time, the Joint Typhoon Warning Center classified it as Tropical Cyclone 01B. With a ridge to its north, the system tracked slowly north-northwestward as banding features improved.[8][9] At 0000 UTC on April 28, the IMD upgraded the system to Cyclonic Storm Nargis while it was located about 550 km (340 mi) east of Chennai, India.[10]

Rainfall rate from cyclone Nargis, as measured by the TRMM

In Sri Lanka the cyclone produced heavy rainfall which led to flooding and landslides across ten districts in the country. The districts of Ratnapura and Kegalle were the most affected, where more than 3,000 families were displaced. Thousands of houses were flooded, with 21 reported destroyed. The rainfall left 4,500 people homeless,[11] and more than 35,000 people were affected on the island.[12] Three people were reported injured on the island, with two others dead.[11]

The India Meteorological Department recommended for fishermen not to sail into the ocean during the passage of Nargis. Strong waves and gusty winds were expected along the Tamil Nadu and Andhra Pradesh coastline in الهند.[10] Additionally, the influence of the cyclone lowered temperatures along the Indian coastline, which had been affected by a severe heat wave.[13]

When the cyclone was originally expected to strike near Bangladesh, officials requested for farmers to hurriedly finish harvesting the rice crop; at the time, the country was experiencing severe food shortages from Cyclone Sidr in the previous year and flooding earlier in the year, and a direct strike from Nargis would have resulted in destroyed crops due to strong winds.[14]
